Dec. 9, 1930. slcKHbLfr S EPARAT OR Filed Nov 7, 1928 Patented Dec. 9, 1930 PATENT OFFICE FRIEDRICH EIGKHOLT, OF GEISWEID, GERMANY v snrlmaron Application filed November 7, 1928, Serial No.

My invention relates to improvements in apparatus for separating dust, water, oil, and the like from air, gas or vapor, and more particularly in apparatus of the type in which a plurality of separating receptacles are disposed in series. The object of the improvements is to provide an apparatus of this type in which the resistance opposed to the current of air or gas is comparatively small, so that the loss of pressure within the apparatus is reduced to a minimum. With this object in view my invention consists in providing an all outer separating receptacle having a tangential supply of the air, gas or vapor, and a separating receptacle disposed within the said outer receptacle and having helically shaped intake pipes and an axial discharge pipe for the gas, the-said intake pipes of the inner receptacle being preferably disposed so as to be directed with their intake ends in opposition to the current of air or gas delivered into the outer receptacle. Preferably, the total crosssectional area of the intake pipes of the inner receptacle and the cross-sectionalarea of the axial discharge pipe are equal to or larger than the cross-sectional area of the intake pipe of the outer receptacle. For separating the foreign matter separated from the air or gas,

the inner receptacle is provided with a bottom in the form of. a valve and adapted to yield against the pressure of a spring for opening the receptacle and permitting the escape of the said foreign matter into the outer receptacle.

My invention also relates to means for controlling. the discharge of the foreign matter separated from the air or gas from the outer receptacle, and the object of the improvements is to provide an apparatus in which the valve controlling the escape of the said foreign matter can not be obstructed by the said foreign matter. With this object in view my invention consists in connecting the said valve with a power operated member adapted to be acted upon by the pressure within the receptacle for opening the valve.

Other objects of the improvements will be explained in connection with the description of the apparatus.

For the purpose of explaining the invention 317,775, and in Germany November 10, 1927.

an example embodying the same has been shown in the accompanying drawing in which In the example shown iii the 7 if 7 apparatus for purifying air, gas or vapor consists of an outer receptacle (1 and an inner receptacle 12 disposed concentrically within the outer receptacle. The air or gas is admitted to the outer receptacle through an intake pipe 0 disposed tangentially of the said receptacle, so that the air or gas taken into the receptacle a has a circular movement, and i the foreign matter is separated from the air by centrifugal action and collected on the bottom d. The inner receptacle b is provided with helically wound intake pipes e. The inner receptacle 5 is mounted on a concentric outlet pipe k extendin through the top of the receptacle a and ending in the receptacle 6 substantially at the middle thereof. The air to be purified is admitted to the receptacle I; through helical intakepipes e having their intake ends substantially at the middle between the axis of the outer receptacle and the wall thereof, the said intake ends being directed against the current of air circulating within the receptacle a. The receptacle b is provided with a yielding bottom 7 bearing on an annular shoulder of the receptacle 5, a spring 9 being provided for normally holding the said bottom on the said shoulder. Thus the bottom f provides a valve for the receptacle 72. Through the helical intake pipes e the air is delivered into the receptacle 1) downwardly and in circular direction, and by the pressure of the said air the bottom is slightly pressed downwardly and away from its seat thus providing a small annular gap h. The foreign matter is thrown by the circulating air against the wall of the receptacle said plate being to prevent the separated foreign matter from being whirled around by the current of air. The purified air is'discharged from the inner receptacle 6 through the axial p1pe The foreign matter separated from the air within thereceptacles a and b is gathered on the bottom d of the receptacle a, and it is adapted to be delivered at suitable intervals of time through a valve it connected with the bottom of the receptacle a. The valve cone u is normally pressed on its seat by a spring w, and its operation is controlled by a plunger or diaphragm s acting on the valve cone through the intermediary of a stem :0. The diaphragm s is located within a chamber y of the valve casing t, and the said chamber is connected by a pipe 1' with a valve block 0 having an axial bore controlled by a valve p. The said valve cone p is adapted to be 0perated by means of a float m provided at the bottom of the receptacle (1. The operation of the controlling'valve is as follows:

As the foreign matter separated from the air rises within the receptacle a the float m rises thus compressing a spring n acting on the valve p. As the float rises its upward pressure is increased, until finally the pressure is suflicient to lift the cone from its seat, whereupon the valve is thrown upwardly by the spring a. It appears therefore that the valve is suddenly opened while the float gradually rises within the receptacle. After opening the valve p, 0 the pressure of the air .within the receptacle a is transmitted through the pipe r to the chamber so that thediaphragm or plunger .9 is forced to the left, and the valve to is unseated for permitting the discharge of the foreign matter from the receptacle a. Now the float m sinks within the receptacle 0, so that the valve cone p is again pressed on its seat by the spring n.

The pressure within the pipe 1' and the chamber y is relieved through a vent '0 provided in the pipe 1-. Therefore, the valve cone u is again placed on its seat after closing the valve 0, p. The operation of the valve u takes only a few seconds, so that the loss of pressure through the vent 'v is immaterial.

By providing power operated means for opening the valve u the valve is completely opened immediately after operating the valve 1), so that even a very viscous emulsion is readily discharged, and by arranging the compressible spring 11. in the manner illustrated and described, the valve p is promptly opened under the upward movement of the float. for the supply of motive fluid to pass from the receptacle a to the chamber y, and the valve is held open for a suflicient length of time, being closed only after the float is sunk to a certain point. Therefore in each operation a large amount of liquid is discharged.
